I have an Omega set up on an expansion dock with one servo expansion, and a small servo plugged into it. Something in the dock stack (dock, omega, or servo expansion, I can't tell) is making a sound that for the life of me sounds exactly like a spinning-disk hard drive doing a lot of reading and writing. It's quiet enough that I may not have noticed it, except that the room I'm in is silent right now.

It's not my computer (which has an SSD, not an HDD). It's not the servo, either. When I put my ear right next to the Omega, it's clear that the sound is definitely coming from one of the boards.

Is this normal? There aren't any moving parts on these boards, so I'm at a loss as to what is making this sound.

Not sure about your router, but on mine, the guest network option that secures it from the regular network (isolation) would also prevent items on the guest network from talking to each other... which makes it pretty useless for IoT unless each Thing is talking via a cloud service. And with isolation off, I'm pretty sure that devices on the guest network can talk to devices on the regular network.

If your router's guest network isolation works differently, I'd love to know which router it is! I may pick one up.

I was actually thinking about setting up one of my Onion Omegas as a separate network for IoT, but right now I've got three hubs (hue, vera, and sinope) that connect via ethernet cable, so I'd have to rig up some sort of switch/mini-router to get them onto the Omega's network. And then I'd still have to figure out how to set it up so that devices on my regular LAN could talk to the IoT network, but not vice versa. Otherwise, there would be issues with control apps that require being on the same network as the devices they control... or again, they'd have to talk via the cloud (and I like to keep things local if at all possible).

I just followed the LAMP stack tutorial and added a very simple test page to /usr/share/htdocs to be sure that php is working.

It's not working. I get a "Forbidden" page, saying I don't have permission to access the file.

I'm very new to setting up apache and php, so I have very little idea of where to start looking for the problem. I'm pretty sure I followed the tutorial exactly as it said to do it. What might I have missed?
